本文采用国产CF钢材对现有的几种损伤参数进行了实际测试考证。并对空穴型损伤发展过程进行了研讨。研究了空穴扩张比R/R_σ与宏观力学效应(Rσ,ε_P)之间的定量关系。建立了新的损伤因子D(V_)来表征材料的损伤程度,它比迄今文献中所提出的各种损伤参量物理意义明确,便于测试和应用。 In this paper, domestic CF steel on the existing several damage parameters for the actual test textual research. And the development of hole damage was discussed. The quantitative relationship between cavity expansion ratio R / R_σ and macroscopic mechanical effect (Rσ, ε_P) was studied. A new damage factor D (V_) was established to characterize the degree of material damage, which is more specific than the damage parameters proposed in the literature so far for ease of testing and application.
